MIXING-MACHINE.

Specification of Letters Patent.

Patented Apr. 2'7, 1915.

To all whom it may concern:

Be it known that I, ALoNzo A. Warren, a citizen of the United States, and a resident of New Britain, in the county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Mixing- Machines, of which the following is a specification.

This invention relates particularly to a machine for mixing together various ingre dients, as for instance in the making of salad dressings, etc., and has for its object to produce a device of this sort having features of novelty and advantage, and particularly to provide means for very thoroughly mixing the ingredients and keeping them always in the mixing zone.

In the embodiment of the invention selected for illustration, Figure 1 is a side view. Fig. 2 is atop view. Fig. 3 is a central verticalsection. Fig. 4 is a detail of the attachment of the beater to its shaft.

In the drawings, a denotes the base which is preferably provided with a screw clamp in order that it may be attached to a table. I) is the bowl supported on the base, and c the cover for the bowl which is engaged by the nuts (1 at the end of the tie rods 6 which are connected with the base and serve to bind the bowl between the cover and the base and so assemble these three parts together. The beater driving mechanism, indicated generally at f, is mounted on the cover. The cover is also provided with an aperture 9 through which ingredients may be introduced into the bowl, and with a funnel it provided with a stopcock i through which oil or other liquids may be fed in such quantities and at such a rate as may be desired.

2 denotes a standard secured to the cover and having a lateral arm 3 from which extends a lateral shaft 4 upon which is mounted the main driving member 5. 6 is a handle also mounted on this shaft and having driving connection with the head of the main driving member 5, and held in position by the nut 7 This main driving member comprises two bevel gears, one 10 at its periphery, and the other 11 near its center. The last mentioned gear meshes with a bevel pinion 12 secured to a shaft 13 which passes through the lateral arm 3 and has secured to its lower end a driving head 14.

Having a bearing in an aperture in the base of the standard 2 is a second bevel pinion 20 which meshes Withthe bevel gear 10 at the periphery of the main driving member. This pinion 20 is formed at the end of a hollow sleeve 21 through which passes the beater shaft 22, the end of which is fitted into a socket in the driving head 14 at one side of its center, forming an eccentric connection of the beater shaft to the driving head. Secured to the beater shaft as by a set screw 23 is a sleeve 24 having a squared lower end 25 which fits within the squared upper end of the sleeve 21, forming a driving connection between the pinion 20 and the beater shaft. This driving connection can be other than that here illustrated and described.

From a study of the mechanism above described it will be seen that the beater is caused to travel around the interior of the bowl, and at the same time is rotated upon its own axis, and the greatest width of the beater is at least equal to and preferably sllghtly greater than one half the diameter of the bowl, the consequent result being that the ingredients cannot get away from the beater but are always and continuously being mixed together by this compound action of the beater.

The bottom of the bowl is concaved as indicated at 25, and the end of the beater is curved to fit the concavity of the bowl as clearly shown at 26 in Fig. 4. The beater also has a slip connection with the shaft through the pin 30 in the shaft working in the slot 31 in the beater, with the result that the beater always rests on the bottom of the bowl. The bottom and side blades of the beater are deeply serrated as indicated at 33, producing a-structure which somewhat approximates the tines of a fork, greatly facilitating the complete and thorough mixture of ingredients.

I am aware that the invention as here described is suceptible of various changes and alterations without departing from the spirit of the invention.

I claim as my invention:

1. In a device of the character described, a bowl, a beater within said bowl, and a heater shaft, driving connections for said shaft, a non-revolnble bearing for said shaft, and means engaging said shaft at the opposite side of said bearing from said beater to cause said beater to move in a circular path within said bowl.

a bowl, a beater therein,

2. In a device of the character described, a bowl, a beater located therein, a beater shaft and a non-revoluble bearing therefor, a driving head and means for rotating it, an eccentric connection between said driving head and beater shaft, 2. gear secured to said shaft at a point between said driving head and heater, and means for rotating said gear.

3. In a device of the character described, a beater shaft, a driving head, the end of said shaft terminating adjacent to said head and eccentrically connected therewith, a pinion having driving connection with said beater shaft between said head and heater, a second pinion having driving connection with said head, and a main driving member having separate gears meshing with said pinions.

4. In a device of the character described, a bowl, a cover therefor, a hollow sleeve fitted in an aperture in said cover and provided with a pinion at its upper end, a beater within the bowl, a beater shaft extending through said sleeve, a tapering polygonal member secured to the beater shaft and fitting within the similarly shaped upper end of said hollow sleeve, a driving head, and an eccentric connection between said head and the upper end of said beater shaft, a pinion connected with said driving head, and means for operating said pinions,

5. In a device of the character described, a bowl, a cover therefor, a standard mount ed on the cover and having a base and a laterally extending arm, a driving gear supported on a hollow sleeve in said base, a vertical shaft extending through said lateral arm, a gear secured to the upper end of said shaft, and a driving head to the lower end thereof, a laterally extending shaft mounted in the end of said arm, a driving member mounted thereon and provided with gears meshing with the two first mentioned gears, a handle slidable on said shaft, interengaging parts on said handle and driving member, a nut threaded onto said shaft to hold the last mentioned parts in engagement, a beater within the bowl, a heater shaft extending through said hollow sleeve and having its upper end eccentrically connected with said driving head, and means secured to said beater shaft and having a driving connection with the first mentioned gear.
